The coating composition is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon in weight ratio. SGCC G550 Color Coated PPGI Corrugated Sheet Prepainted Metal Steel Plate Roofing Sheet process of galvanized steel sheet is similar to that of galvanized steel sheet and aluminized sheet, and it is a continuous molten coating process. The galvanized steel sheet with 55% aluminum-zinc alloy coating has better corrosion resistance than galvanized steel sheet of the same thickness when exposed to the same environment on both sides. The 55% aluminum-zinc alloy coated aluminum-zinc steel sheet not only has good corrosion resistance, but also the color-coated products have excellent adhesion and flexibility.DX52D+AZ/DX51D+AZGalvalume/galvamized Steel Coil can be customized according the custom’s d......

It is mainly produced by continuous galvanizing process, that is, the rolled steel plate is continuously immersed in a plating tank with zinc melted to make galvanized steel plate; alloyed galvanized steel plate. This kind of steel plate is also manufactured by hot dip method, but immediately after being out of the tank, it is heated to about 500 ℃ to form an alloy coating of zinc and iron. This galvanized coil has good paint adhesion and weldability.
